28 The heart of the righteous yponders how to answer,
but zthe mouth of the wicked pours out evil things.
23 kA prudent man conceals knowledge,
kbut the heart of fools proclaims folly.
16 qEvery prudent man acts with knowledge,
rbut a fool flaunts his folly.
2 A fool takes no pleasure in understanding,
but only zin expressing his opinion.
